Experimental and Numerical Studies on Chemically Active Flame Inhibitors
Fire hazards pose an increasingly potent threat to modern societies. Early identification and mitigation of fire hazards are crucial to avoid the loss of human lives and property. Recent research suggests that finely-atomized ...
Physical insights into unstart dynamics of a hypersonic mixed compression intake
Hypersonic air-breathing cruise vehicles powered by supersonic combustion ramjet engines
are the potential candidate for future space and defense applications. The air intake of the
scramjet engine is a vital component ...
An Experimental Investigation of Transitional and Turbulent Channel Flow
This thesis is a comprehensive experimental investigation of transitional and turbulent channel
flow in the Reynolds number range of Reτ = 55 − 1559. Towards this objective, a new
channel flow facility was designed and ...
On late stages of transition in round jets
A round jet is one of the simplest canonical axisymmetric free shear flows that occur both
in engineering applications and natural phenomena. A laminar-turbulent transition process
is inherent to its development involving ...
Implicit Gradient Reconstruction for Unstructured Mesh Finite Volume Method
In the present work, an Implicit Gradient Reconstruction (IGR) method is proposed in the
context of Finite Volume Methodology (FVM). There are three computationally intensive steps
involved in a typical finite volume ...
Numerical Study of Accelerating Turbulent Boundary Layers
This thesis focuses on the prediction of favourable pressure gradient turbulent boundary layer flows. Particularly, the focus is on mild favourable pressure gradient turbulent boundary layers and relaminarising turbulent ...
Standoff Target Tracking Guidance using Line-of-Sight Distance Bifurcation
Unmanned aerial vehicle (UAV) applications that continue to receive significant attention are target acquisition and tracking. There exist many paths to track a stationary target from a prescribed altitude. The most widely ...
Efficient Finite Element-Based Approaches for Solving Potential Flow Problems in Fluids
For many years, fluid flows have been modeled, starting from basic potential flow equations to full Navier-Stokes equations. The complexity of the flow increases as viscous effects, boundary layer, and flow separation are ...
Classical Approach to Understanding the Impact Dynamics of Hollow Droplets
Compound droplets are utilized in applications ranging from the preparation of emulsion to
biological cell printing and additive manufacturing. Here, we report on the impact dynamics of
a compound hollow droplet on a ...
Torque transport, mean velocity profiles and turbulent statistics of a wide-gap Taylor Couette flow
Wall-bounded turbulent flows that possess finite curvature of the mean flow streamlines are known to be starkly different from their
plane counterparts. One of the primary distinguishing features of such flows is the ...
